Neil and I agree to disagree a little on this point. Yes there are some who have that one and only problem. Come here ask the question get a answer and are gone. But there are also a lot of people that after looking around realize just reading these threads and hearing of others troubles and solutions realize that's something worth remembering and start getting more and more DIY bug. The third group I think I might fall into and that's I just enjoy reading about this stuff even though I have done it for 50 years. Learning new stuff and helping people with stuff I do know.
